89H48H12G2ZCBLG8

Overview

The 89H48H12G2ZCBLG8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation. It functions as a PCI Express switch providing 48 lanes and 12 ports of high-performance system interconnect switching. The device utilizes a non-blocking architecture optimized for deterministic throughput across multiple traffic flows. It operates with a supply voltage of 3.3V and is housed in a 676-FCBGA package measuring 27x27 mm. The component supports industrial temperature grades and complies with RoHS3 standards.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput regardless of switch loading
• Partitionable design enabling true multi-root support capabilities
• Internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Applications

• High performance system interconnect switching
• Multi-root server architectures
• Storage area network infrastructure

Procurement Notes

This specific part number is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging options such as reel variants. Engineering samples are not currently available through standard channels. Compliance with environmental regulations including RoHS3 should be confirmed via current datasheets before integration into new designs.

Selection Notes

Designers requiring this functionality must consider that the base model is discontinued. Alternative packages within the same family, such as the ZCBLGI8 variant, may offer different moisture sensitivity levels or lead-free status. Evaluation boards like the 89KTPES48H12G2 provide reference designs for validating switch functionality during the development phase prior to hardware finalization.

Part Context

This component belongs to the 89HPES48H12G2 series of PCIe Gen2 switches. It shares architectural similarities with other models in the 89H48H12G2 family but differs in packaging and termination specifications. The device is designed to replace legacy interconnect solutions requiring high bandwidth and low latency for complex system topologies.

Replacement Considerations

Publicly confirmed substitute part numbers include 89H48H12G2ZCBLGI8 and 89H48H12G2ZCBLG. These variants maintain the core switching functionality while potentially differing in lead content or reel packaging configuration.
